Chapter 3: Q. 3.7 (page 66)

Indicate whether each of the following describes at gas, a liquid, or a solid:

a. The breathing mixture in a scuba tank has no definite volume or shape.

b. The neon atoms in a Fighting display do not interact with each other.

c. The particles in an ice cube are held in a rigid structure.

Short Answer

Expert verified

a. The breathing mixture is a gas

b. The neon atoms is a gas

c. The particles in an ice cube is a solid

Step by step solution

01

Given Information (a)

(a) Is the breathing mixture in a scuba tank are gas, a liquid, or a solid?

02

Explanation (a)

(a) The breathing mixture in a scuba tank is a mixture of several gases like Oxygen, Nitrogen and some trace amounts of Argon. Since gases have no definite volume or shape, the scuba tank mixture is in gaseous state.

03

Given Information (b)

(b) Are the neon atoms in a fighting display are gas, a liquid, or a solid?

04

Explanation (b)

(b) The atoms don't interact with one another, indicating that the distance between atoms is large. Therefore,it's a gas.

05

Given Information (c)

(c) Are the particles in an ice cube are a gas, a liquid, or a solid.

06

Explanation (c)

(c) Rigidity is the property of solids. Since the statement describes the ice cube as having a rigid structure, it is solid.
